. To all whom t may concern Be it'lrnown that l, EDWARD THOMAS, a citizen of the United States, and a resident of the city of East Chicago, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Aru-l The invention consists in the combinations and arrangements ofparts h'ereinafterdescribedan'd claimed. l y The invention will be best understood by reference to thel accompanying drawings forming a part of Vthis specification, and in which, y l

Fig. l, is a longitudinal view of an apparatus embodying the invention and shown as mounted on the driveJ shaft of an ordinary a.uto1 nobile,4 f

Fig.v2, an enlarged section Vtaken on line 2 2 of Fig.`l, Fig. 3, anenlarged partial longitudinal section through the apparatus,

Fig. 4, a` section taken on line 4-4 of Fig. 3, f s Fig. 5, a section takenl on line 5-5 of igf a detail view offa'n actuating member employed in the construction, and

F ig. 7, `a detail view of a clutch member employed in the construction.`

The preferred form offconstruction, as illustrated in the drawings, comprises a suitable casing 8 mounted on the automobile7 enclosing a portion of the drive shaft y 9 thereof'. Alarm signal bells 8 are mounted on opposite sides of 'casing 8, as shown,

V and operating hammers l0 are pivoted at 11 to the sides of casing 8y in operative relation withsaid bells, actuating springs l0 being connected with said hammers to actuate same. Each of the hammers l0 is in substantially U-form and is provided on itsouter end` with a hammer head l2, arranged to strike the corresponding bell 8', and the other side of each hammer passes through a suitable slot 13 in the rear wall of the casing 8 and is equipped with a lug or ear 14 adapted to lc'eive a clutch tooth 18 on ftheforward face engage radiating pins l5` onan.actuating'` `disc 16 .loosely; mounted fon .drive shaft`9.

The actuating disc 16, is provided in its rear j face with a lclutch recess lnadapted to .re-

of a clutch member 19- xed on shaft 9. Aci tuating 'member 16 is -pro-"vided- 'on' its-forward side With a hub `2O having a4 "roove 2ly l therein-adaptedfto receive a fori; 22 car: ried by a reciproca-ting actuating rod 23 opy erating'through a suitable guide opening in' 1l thev forwardside of casing S- and operatively connected with varaclrv bar 24. A;.coiiipresfl sion spring25 is imprisonedbetween the4- y Y .milf serves to normally h'old'theiclutcli members 1 forli 22 and the forward wall of casingSv and on memberslt and 19in engagement; Rack bar 24 meshes with the pinion 24 on aver-` tical shaft 26 extending upwardly'under theA :i i i' i.

edge of the drivers seat of vthe. automobile,y .-.L'it its upper end 'shaft `26 carries a springheld operating larm 27 adapted to engage a .K

lug or fil1ger23 on the under side of the operators seat29, and wherebyjsaid shaftmay be locked in position to holdlthe vclutch mem vbers 17-18 out of engagement.v

ln use, when the driver leaves his car, he

releases the shaft v26,.permitting of engagef of the driver or ofpassers by, thus frustrating the attempt. ,When the driver desires to operate the car normally,`` he simplylactuates the shaft v26 todisengagethe clutch members 17-18 and vlocks the same in with# `drawn position yby engaging arm 27 behind finger 28, whereupon the automobile may'- -ment between clutch membersflY-ltl and l l be operatedin the usual manner without givingan alarm signal. j n.

llhile l have illustratedand `described the preferred form of construction for carrying y my inventionv into effect, this is capable of f' variation4 and modification withoutjdeparting from the spirit of the' invention. l..

'ther-erom, la@ not Wight@ be limited tothe rec'ise details of construction gset forth, but

)desire to avail myself of such variations and modifications as come within `the scope of the appended claims. 4

-lavinodescribed my invention, what I 10or f claim as new and desire to secure by Letters Patent is sl. The combination with a shaft of an automobile, of an audible signal in operative relation therewith; spring actuated means for placing said shaft in operative connection with said signal; manuallyvoperable means for disconnecting said signal from said shaft; and locking means for locking said parts in inoperative position, substantially as described.

2. rllhe combination with a shaft ofi an automobile, of a signal bell in operative relation therewith; a spring-actuated hammer arranged to sound said bell; an actuating and a clutch member mounted on said shaft; one oi said members being fixed to said shaft and the other loose thereon; a spring normally holding said actuating and clutch -members in operative engagement with each other; manually operable means Jfor separating said members; and a'loclr for locking said members in separated condition, substantially as described.

3. The combination with a shaft of an auf` tomobile, of a signal bell in operative relation therewith; a spring-actuated hammer arranged to sound said bell; an actuating and a clutch member mounted on said shaft,l

one of said members being xed to said shaft and the other loose thereon; a spring normally holding said clutch and actuating members in operative engagement with each other; an actuating rod arranged to sepa- -ratesaid-members; a rack bar on said rod;

of an automobile., of a casing enclosinga ating pins adapted to strike said hammers to sound said bells; a clutch vXed. to said sha-ft and arranged to engage `saidactuating member upon longitudinal movement of the latter on said shaft; awforl engaging said actuating member to effect longitudinal movements `thereof on said shaft and permit rotations thereof; a reciprocating actuating rod connected withlsgaid forli; a spring imprisoned between said fork and a`wall of said casing and arranged toI normally press said actuating member into engagement with said clutch; a rack/bar operatively connected with said actuating` rod; a pinion-meshing vith said racir bargan actuating shafttixed to said pinion andl arranged inoperative 'relation with the automobile drivers seat; and means -lior loclringsaid shaft in position to withhold said actuating member-twin,en-y gagement with said clutch;substantially as described.

ri`he combination with a vehicle having a part moving with each movement ot thc vehicle. of a mechanically operated alarm"v mounted upon the` vehicle, and provided with movable parts engaging with-the moving parts oi' the vehicle and actuating said alarm on movement ofsaid vehicle, irrespective 'oi'r direction7 and private means for rendering said falarm'inoperative;

6. rihe combination witha vehicle having" a part moving with each movement of the vehicle, of a mechanicallyoperated alarm, and means for oper-ating said alarm oomprising; -a rotatable member, means'v for dri ving` said rotatable lmember from saidmovi a:

t part, means 'iorleperatingsard mec-hanical alarm irrespectiveio'f the direction of rotation driven by said` rotatable-member, and

means for moving'Y said rotatable v-memlvisr into 'and out 'of engafgement` yWi-thsaid driving'means and private means for rendering said alarm inoperative.

lin testimony whereof I have signed my name to this specification in the-presence 'of two subscribing witnesses. l
